' EDWARD Gr. DURANT AND ELI SHUFE, OF RAGINE, WISCONSIN; SAID SHUPE I ASSIGNOR TO THOMAS KANE, OF CHICAGO, ILLINOIS.

OPERA-CHAIR.

SPECIFICATION forming part of Letters Patent No. 294,454, dated March 4,1884.

v Application filed July 11, 1883. (No model.)

To all whom it may concern:

Beit known that we, EDWARD G. DURANT and ELI SHUPE, of Racine, in the county of Racine and State of Wisconsin, have invented certain Improvements in .Opera- Chairs and other Folding Seats, of which the following is a specification.

This invention relates more particularly to that class of opera-chairs and other seats in which the seat proper and the back are journaled or hinged in such manner as to swing upward to a vertical position when not in use, and are connected with each other by devices adapted to secure a simultaneous movement to and from an operative position.

The invention consists in combining with the seat-supporting arm and the back-supporting arm a stud on one of said members and an arm extending from the opposite member and engaging with said stud, whereby the move ment of 'one arm is caused to impart a corresponding movement to the other.

Referring to the accompanying drawings, Figure 1 represents a side elevation of a portion of a seat-standard with my improved arm applied thereto, the arms being represented in position for use. Fig. 2 represents a similar view of the parts as they appear when closed or folded. Fig. 3 isa crosssection on the line as x.

Referring'to Figs. 1, 2, and 3, A represents a rigid supporting -'standard, which may be made of any suitable size and form and se-, cured firmly in position at its base. l? represents the seat-arm, and O the back-arm, the two arms being pivoted independently to the standard either upon journals or pivots formed upon the standard, as shown, or in any other The back-arm O has rigidly suitable manner. secured to or formed upon it a forwardly-extending arm or projection, D, the forward end of which is provided with a longitudinal slot,

into which there extends a stud, E, formed 4 upon the seat-arm, the proportion and arrangement of the parts with respect to each other being such that upon turning the seat upward to avertical position the stud operating'in the slotted arm causes the back to assume a corresponding position, and upon turning the seat downward to a horizontal posi- 5( tion, occupied when in use, it causes the back to assume the slight inclination required.

It will of .course be understood by those familiar with the subject that each chair will embrace two standards and its two arms, 10- cated on opposite sides of the chair, the seat proper and the back proper being each supported by arms at its two edges, as usual in this class of furniture. The seat and back proper, being inserted between and secured 6c to the arms at their opposite edges, will serve to hold the arms outward in proper position upon the journals or trunnions, as in other furniture of this class; but, if desired, bolts or equivalent fastening devices may be'passed 6 centrally through both the arms and the standard.

We are aware that swinging back and seat arms have been connected by links pivoted thereto by intermediate springs and various 7C other devices, and to such constructions we lay noclaim, our invention being restrictedto the particular construction and combination of parts herein described. .1

Having thus described our invention, what we claim is- 1-. In combination with a supporting-standard, a seat-arm and a back-arm pivoted there to, oneof said arms provided with a stud, and the other arm provided with a rigid slotted 8c projection mounted upon said stud, as described and shown.

2. The combination of the standard A, the seat-arm B, pivoted thereon and provided with the stud E, and the back-arm 0, also pivoted 8 to the standard and provided with the rigid slotted extension D, loosely engaging the stud, as shown, whereby the two arms are caused to movesimnltaneously and positively in both directions.
